5f1fd50f6a Used a forward declaration of classes fgTILE and fgMATERIAL to eliminate 
the need for "void" pointers and casts.
Quick hack to count the number of scenery polygons that are being drawn.

ab51d8ca5c Need to negate the test for textures so that textures aren't loaded when 
they are disabled rather than visa versa ... :-)

d212b2d459 material.cxx: don't load textures if they are disabled 
obj.cxx: optimizations from Norman Vine
tile.cxx: minor tweaks
tile.hxx: addition of num_faces
tilemgr.cxx: minor tweaks

adee4bc151 Added far clip plane to fragment clipping calculations and tie this to 
weather->visibility.  This way you can increase framerates by increasing
for and lowering visibility.

262b2f0607 Added ground collision detection. This involved: 
- saving the entire vertex list for each tile with the tile records.
- saving the face list for each fragment with the fragment records.
- code to intersect the current vertical line with the proper face in
  an efficient manner as possible.
Fixed a bug where the tiles weren't being shifted to "near" (0,0,0)

6d48ba08a0 Added automatic mipmap generation.

rather than recalculating it with push() translate() pop().

be9d6ea4ea Check for GL_VERSION_1_1 or GL_EXT_texture_object to decide whether to use 
"EXT" versions of texture management routines.

Working on rewriting the tile management system so a tile is just a list
fragments, and the fragment record contains the display list for that fragment.

70fae724a7 Moved global ref point and radius (bounding sphere info, and offset) to

compensating for it on the fly.

ed0acbad5b Minor transformation adjustments to try to keep scenery tiles closer to 
(0, 0, 0)  GLfloats run out of precision at the distances we need to model
the earth, but we can do a bunch of pre-transformations using double math
and then cast to GLfloat once everything is close in where we have less
precision problems.
